Usage example:
docker run --name emailrelay \
-v /etc/ssl/private/key_and_cert.pem:/etc/ssl/server.pem:ro \
drdaeman/emailrelay \
-D msa.example.com --immediate --forward-to mail.example.org:smtp \
--server-tls /etc/ssl/server.pem --client-tls
To get help, check emailrelay documentation or use:
docker run --rm drdaeman/emailrelay --help
Note, the --remote-clients --port $PORT (and some more) options are
passed automatically, so to change client port just redefine the PORT
environment variable. The default port number is 587.
For a full control, run a full command starting with emailrelay, i.e.:
docker run drdaeman/emailrelay emailrelay --help
